The main purpose of this legislation, known as the "Full Cost of War Act," is to ensure that any future military actions authorized by Congress include funding for the Department of Veterans Affairs. This funding is intended to cover the medical care, disability compensation, and other benefits that veterans may need as a result of their service in these military operations. Key provisions of the Act require that any authorization for the use of military force or declaration of war must also include a specific allocation of funds for the Department of Veterans Affairs.
